AD NUMBER: 2005-22-12
MANUFACTURER: General Electric
SUBJECT: Airworthiness Directive 2005-22-12
SUMMARY: The
FAA is adopting a new airworthiness directive (AD) for General
Electric Company (GE) CF6-80E1 series turbofan engines installed on
Airbus Industrie A330 series airplanes.

This AD requires a check of the holding torque of the thrust
reverser actuation system (TRAS) locks, and if necessary a visual
inspection of the TRAS lock flexible drive shafts, within 10 flight
cycles after all aborted takeoffs in which the thrust reverser was
deployed.

This AD results from reports of operators finding several
damaged TRAS lock flexible drive shafts during inspections and
checks of the drive shafts.

We are issuing this AD to prevent inadvertent in-flight
deployment of the thrust reverser, which can result in loss of
control of the airplane.
